coccinelle: orplus: reorganize to improve performance
Adding two #define constants is less common than performing & and | operations on them, so put the addition first to reduce the set of cases that have to be considered in detail. At the same time, add & and | patterns for both arguments of +, to account for commutativity and obtain more results. Running time is divided by 3 when applying this to the whole kernel on my laptop with an Intel i5-6200U CPU.
